Krabi Emerald Pool & Hot Springs Guide: Natural Hydrotherapy & Jungle Baths
Located in the Khao Phra Bang Khram Nature Reserve roughly 70 kilometers southeast of Ao Nang, The Emerald Pool (Sa Morakot) and nearby Klong Thom Hot Springs represent Thailand's premier natural outdoor hydrotherapy experience.
The Emerald Pool Experience
Fed by subterranean thermal streams flowing from the limestone hills, the Emerald Pool is a 115-square-meter natural swimming basin filled with crystal-clear, mineral-rich water that glows vibrant turquoise green due to high calcium carbonate and mineral content. An elevated wooden boardwalk winds through the virgin lowland rainforest, passing smaller jungle springs and bird-watching hides.
Klong Thom Thermal Cascades
Just a 15-minute drive from the Emerald Pool, Klong Thom Hot Springs features thermal mineral water bubbling from underground volcanic chambers, cascading down smooth polished river stone ledges like natural hot tubs into the cooler jungle stream below. The soothing sound of rushing water combined with natural forest canopy provides a deeply restorative escape.
Practical Visitor Advice & Etiquette
- Park Hours: The reserve is open daily from 08:30 to 16:30. Arrive before 10:00 AM to enjoy the pools before tour vans arrive.

Natural Hydrotherapy + Thai Massage
Combining 30 minutes of thermal hydrotherapy with an afternoon Thai herbal compress massage back in Ao Nang stimulates deep vascular dilation, alleviates joint stiffness, and induces deep, restorative sleep.

Can you swim in the Blue Pool (Sa Nam Phut)?
